Hi,
83 240D body with 84 300SD engine stuffed in. Manual tranny behind it all. 240D did not have overboost protection. I have what I think is the overboost thing from the engine donor car. I need advice on the best way to get this back in the system. Does anyone have a diagram laying out how the overboost gets connected? (both vacuum and electrical?) I have looked over the FSM diagrams, but I am unfamiliar enough with the system to not be sure of what I'm looking at. Also, since the manual tranny 240D doesn't have a tach, what is the best way to adjust the ALDA? Or is my only option to steal the tach from the donor car and trade out my clock for the tach/clock unit? I'm trying to tweak my fuel consumption which is averaging about 23 mpg for about 50/50 hwy/city. Best I have gotten is 27mpg for about 260 miles of flat but windy driving. Also, slightly off topic, does anyone know what brand was "original equipment' for the wheel bearings? Thanks in advance for your help.
